Okay, had a blast doing some runs last night... 1/8 mile, untimed... the iPhone App only (I'm not interested in all the pro/con debate about the iPhone app's, so save it... it's been used against itself, and been consistent against itself, and been all I have at the 1/8 track). I've used Dynolicious a lot now both before having the dyno tune *and* after the dyno tune. Below is the comparative results. Definite improvements since having the Dyno tune.
Also, for those that disregard anything the Dynolicious app has to say *and* for those that don't/didn't read the thread, the before/after actual Dyno results are re-included below too.
The results do not lie... and the L99 stories that are being reported are as consistent as the before/after results people are posting. The results at the track - amazing. As it happens, I lined up next to another 2010 L99 last night. Mechanically the same car as my own... but still suffering from bad timing and a "safe" A/F mixture. I beat it by nearly two car lengths in an 1/8 mile.
